A flash flood watch is in effect for the entire Capital Region as another batch of scattered showers and thunderstorms is expected to roll into the area Monday afternoon.

The rainfall could be most severe points south and east of Albany, including Columbia County, where some places saw more than 4 inches of rain from powerful storms Sunday afternoon. The oversaturated soil there and other places could lead to floods, the National Weather Service said.

"Any places that got a lot of rain yesterday, if they get a few more inches today on that wet soil, that's what we're concerned about when it comes to flooding," said Tom Wasula, a weather service meteorologist.

While early predictions show that rain could be heavy south and east of Albany, Wasula said it's possible that patches of strong storms could develop anywhere in the region.

The rain should begin to fall in the Albany area anytime between noon and 3 p.m., persisting until sunset, Wasula said.

Parts of Schenectady County saw heavy rainfall Sunday as well and could be at risk for flooding Monday, too. In Niskayuna, 1.68 inches of rain fell Sunday, according to weather service data.

An inch of rain fell on parts of Schoharie County and Albany saw a little less than an inch, according to weather service data. About a half inch of rain dropped in most of Saratoga and Rensselaer counties.

Parts of Columbia County were crushed by Sunday's storms. In Taghkanic, 4.84 inches of rain fell and a man was struck by lightning. Around 2 inches fell on many other parts of the county. Several roads were washed out and briefly closed because of the rain.

Monday's rain will add to what has already been an remarkably wet summer. As of Monday morning, 10.34 inches of rain had fallen in Albany since June 1, more than twice the 4.69-inch average for the date.

The rainfall will, however, help to usher in some cooler, drier air. Under high humidity, temperatures have peaked at or above 90 degrees three times in July and have been at or above 87 every day since July 2, according to weather service data.

Highs in the Capital Region are expected to peak around 85 Monday and peak around that mark for the next few days. Temperatures are expected to drop down into the low 80s Thursday and into this weekend.

"It's certainly going to feel a lot nicer out than at has been lately," Wasula said.
